Zenna Atkins, the chairman of the Office for Standards in Education (Ofsted), has raised some eyebrows by saying that, "every school should have a useless teacher." She stresses that schools shouldn't seek out or tolerate bad teaching, but thinks bad teachers provide a valuable life-lesson. From the article: "... on Sunday Ms Atkins told the BBC that schools needed to reflect society, especially at primary level. 'In society there are people you don't like, there are people who are incompetent and there are often people above you in authority who you think are incompetent, and learning that ability to deal with that and, actually surviving that environment can be an advantage.'"
grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."
Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."
